Review ROCKSHOX Monarch Rl Air Rear Shock 165mm 38mm Mtb Black/gray/blue

The **RockShox 46T 31682465 Monarch RL Air** is a premium, high-performance rear suspension designed to elevate your mountain biking experience with unmatched versatility, durability, and precision. Engineered for riders seeking a balance between comfort, control, and efficiency, this air-sprung shock delivers a seamless blend of travel and responsiveness, making it an ideal choice for enduro, trail, and cross-country disciplines. With a **165mm of travel**, the Monarch RL Air provides ample cushioning to absorb the harshest impacts from rough terrain, from rocky descents to deep ruts, while its **38mm internal diameter** ensures robust durability and consistent performance under heavy loads. The **RL (Remote Lockout)** feature allows riders to instantly switch between full suspension engagement and a rigid rear end with a simple pull of the lever, offering unparalleled adaptability for climbing, technical sections, or aggressive descents. Constructed with RockShox s signature **31682465-grade materials**, including a **black-powder-coated frame** for enhanced corrosion resistance and a sleek, aggressive aesthetic, this shock is built to withstand the rigors of demanding rides. The **black, gray, and blue color scheme** not only adds a striking visual appeal but also complements a wide range of bike setups, from aggressive downhill rigs to nimble trail bikes. Whether tackling steep climbs or carving through technical singletrack, the Monarch RL Air s **adjustable air spring** and **dual-path rebound damping** ensure a tailored ride feel, allowing for fine-tuned adjustments to match your weight, riding style, and terrain preferences. Backed by RockShox s reputation for innovation and reliability, this shock is a testament to cutting-edge suspension technology, designed to push the boundaries of what s possible on two wheels.

### **RockShox 46T 31682465 Monarch RL Air Rear Shock (165mm, 38mm) Pros and Cons**

#### **Pros**

1. **High-Quality Construction** The Monarch RL is built with RockShox s premium materials, including a durable aluminum fork crown and a robust air spring system. The 38mm stanchion diameter provides excellent stiffness and resistance to lateral flex, making it suitable for aggressive riding styles.

2. **Adjustable Air Spring** The air-sprung design allows for precise suspension tuning via RockShox s **Reverb** remote or **Quick Release (QR) valve**. This makes it easy to adjust sag, rebound, and compression damping to match rider weight, terrain, and preference. The **35mm air chamber** offers a wide range of adjustability, from plush comfort to firm performance.

3. **Progressive Damping** The Monarch RL features RockShox s **RL (Reverb Lockout)** system, which provides **three damping modes**:

- **Full Damping (Standard)** Best for all-around performance.

- **RL Lockout (Lockout Mode)** Engages a secondary damping chamber for firmer, more predictable feel, reducing bottom-outs and improving pedaling efficiency.

- **RL Soft (Soft Mode)** Reduces damping for a plusher, more forgiving ride, ideal for rough terrain or heavier riders who want extra comfort.

This adaptability makes it versatile for different riding conditions.

4. **Durability and Longevity** The Monarch RL is designed for demanding use, with reinforced components and a robust build that resists wear from frequent use. The **38mm stanchions** and **aluminum crown** contribute to a longer lifespan compared to entry-level shocks.

5. **Compatibility with RockShox s Ecosystem** If you already own other RockShox components (e.g., forks, handlebars, or levers), the Monarch RL integrates seamlessly with RockShox s **Reverb** system, allowing for unified adjustments across your bike.

6. **Good for Aggressive Riding** The firm damping and lockout mode make it well-suited for **downhill, enduro, and aggressive trail riding**, where stability and control are critical. The **165mm travel** strikes a balance between comfort and performance for riders who tackle rough terrain.

7. **Reliable Brand Reputation** RockShox is a trusted name in suspension technology, known for innovation and durability. The Monarch RL is part of their mid-to-high-end lineup, offering a balance between performance and value.

#### **Cons**

1. **Higher Price Point** Compared to budget rear shocks (e.g., Fox Float, DT Swiss, or entry-level RockShox models), the Monarch RL is more expensive. The price reflects its advanced features, but it may not be justified for casual riders or those on a tight budget.

2. **Complexity for Beginners** The **Reverb system** and multiple damping modes can be overwhelming for new riders. Adjusting sag, rebound, and lockout settings requires some learning, and improper tuning can lead to an uncomfortable or unsafe ride.

3. **Weight** At ** 1.5 kg (3.3 lbs)**, it is heavier than some carbon or lightweight aluminum shocks. While not excessively heavy, it may feel noticeable on a lightweight bike or for riders prioritizing minimal weight.

4. **Maintenance Requirements** Like all air-sprung shocks, the Monarch RL requires occasional **air spring maintenance** (checking for leaks, topping up air pressure, and ensuring the QR valve is functioning). Over time, seals and internals may wear out, requiring servicing every **2 3 years** or **50 100 hours of use**, depending on conditions.

5. **Limited Travel for Some Riders** The **165mm travel** is suitable for most trail and enduro bikes but may feel short for **downhill or aggressive riders** who prefer longer travel (e.g., 180mm ). Conversely, it might be excessive for **cross-country or lightweight trail bikes**, where shorter travel (120 140mm) is more efficient.

6. **Potential for Bottom-Outs on Extreme Terrain** While the lockout mode helps, the Monarch RL can still bottom out on **very rough or technical descents** if not properly tuned. Riders pushing hard on steep, rocky, or rooty terrain may need to fine-tune sag and damping to avoid this.

7. **Compatibility Issues with Some Bikes** The **38mm stanchion diameter** and **axle spacing** (likely **12x148mm or 12x150mm**) may not fit all bikes, especially older models or those with non-standard rear dropouts. Always verify compatibility before purchasing.

### **Conclusion**

The **RockShox 46T 31682465 Monarch RL Air Rear Shock (165mm, 38mm)** is a **high-performance, versatile, and durable** suspension option that excels in **aggressive trail, enduro, and downhill riding**. Its **adjustable air spring, progressive damping, and lockout mode** make it one of the best mid-range shocks for riders who demand precision and adaptability. However, its **higher cost, complexity for beginners, and maintenance needs** may not make it the best choice for casual riders or those on a budget.

If you prioritize **performance, adjustability, and longevity** and can justify the investment, the Monarch RL is an excellent upgrade. For **casual trail riders or those seeking a simpler, more budget-friendly option**, a **Fox Float, DT Swiss, or lower-tier RockShox shock** might be more suitable.

---

### **Recommendation**

**Buy the RockShox Monarch RL if:**

- You ride **aggressively** (enduro, downhill, technical trails) and need a **firm, responsive shock**.

- You want **adjustable damping** and the ability to switch between **lockout and soft modes**.

- You already own **RockShox components** and prefer a **seamless integration** with the Reverb system.

- You are willing to **maintain the shock properly** and invest in a **long-term, high-performance suspension**.

**Consider alternatives if:**

- You are a **casual rider** and don t need advanced features.

- You prefer a **lighter or simpler shock** (e.g., Fox Float, DT Swiss, or a lower-tier RockShox model).

- Your budget is tight, and you can find a **well-used Monarch RL at a discount** (though always check for wear).

- You ride **mostly cross-country or lightweight trail**, where **shorter travel (120 140mm)** would be more efficient.

**Final Verdict:** The Monarch RL is a **top-tier choice for serious riders** who want a **reliable, high-performance rear shock** with unmatched adjustability. For most trail and enduro riders, it is a **worthwhile investment** that will significantly improve ride quality and control.
